Dirty Tricks on the Internet

Via Atrios, I came across this WSJ article about a blog operator, Aaron Wall, being sued by a company called Traffic-Power.com for defamation and publication of trade secrets because of comments posted on Mr. Wall's blog, SEOBook.com.

I don't do any business with Traffic-Power so I can't cease doing business with them and my boycotting them would have no effect, but if I did do business with them, this kind of tactic, which can't help but chill the free exchange of information on blogs, would lead me to sever my relationship.
